Stones Corner, Brisbane
From living in Brisbane and shopping in brisbane, i have found that clothes and items in general are usually less expensive the further you get from the city, im not saying there's no bargains in the city... but if i go on a shopping spree i usually stick places like stones corner or the hyperdome at logan,
These places have reasonable priced shops with decent clothes.
What to buy: clothes :P
What to pay: depends what you get, i usually get a few good outfits for $50 A
